“…The case studies show a relatively small variation in gas flow properties. However, increasing the diversity in gas supplies may require a revision of gas safety regulations and appliances operating in a wider Wobbe index range [19,20]. Discussed research being carried out in realizing these appliances for future applications.…”

“…Amidst these variations, appliance burners have to perform satisfactorily without readjustment on fuel gases that vary considerably in their combustion characteristics from the gas mixture on which the initial adjustment was made. Extensive research has been undertaken for ways to predict the interchangeability of one gas with another [17][18][19][20]. It was recognized that correlation of heating values and specific gravities alone was insufficient, and a third factor, namely flame characteristics which depend on chemical composition, must be included.…”

h i g h l i g h t sA steady-state analysis method for gas networks was developed. This method is used for gas networks with distributed injection of alternative gas. A gas network with injection of upgraded biogas and hydrogen was simulated. Results show the impact on pressure and gas quality in the network. a b s t r a c tA steady state analysis method was developed for gas networks with distributed injection of alternative gas. A low pressure gas network was used to validate the method. Case studies were carried out with centralized and decentralized injection of hydrogen and upgraded biogas. Results show the impact of utilizing a diversity of gas supply sources on pressure distribution and gas quality in the network. It is shown that appropriate management of using a diversity of gas supply sources can support network management while reducing carbon emissions.

“…Although natural gas is an attractive fuel in many respects [56], given the rapidly dwindling reserves and the environmental pollution it causes, it is not the ultimate solution to energy problems. In this respect, hydrogen has more potential.…”

“…Firstly, substituting a portion of the natural gas supply with hydrogen would reduce diffuse CO 2 emissions. If 10% of the natural gas was to be exchanged for hydrogen, a 3.6% emission reduction would be achieved -this corresponds to 6 Mton CO 2 savings, which would already amount to half the Kyoto obligation of the Netherlands [56]. Secondly, it would allow gradual learning of how to deal with hydrogen in the context of an already mature natural gas system.…”

“…Secondly, it would allow gradual learning of how to deal with hydrogen in the context of an already mature natural gas system. Mixing H 2 into the natural gas network, several technical and economic hurdles for using hydrogen could to be cleared (see [56]). The blending, approach promises to ease a shift towards a hydrogen economy.…”

Surplus renewable energy can be converted to hydrogen by way of electrolysis. In some cases, injection of the resulting hydrogen as renewable gas into the natural gas pipeline system may result in increased social and environmental benefits at lower overall costs than delivering additional renewable energy as electricity. The result would be increased utilization of installed renewable generation capacity, such as wind or solar facilities. This article reviews key issues related to the option of injecting hydrogen into natural gas pipeline systems, including impact on end‐use systems, safety, material durability and integrity management, leakage, and downstream extraction.
